Jennifer Lopez teamed up with UNICEF to put out a video urging kids to collect donations this October, with benefits going towards Hurricane Maria relief efforts in J. Lo's family's home island of Puerto Rico. J. Lo appeared in an ad posted to YouTube and directed towards the children who can make a difference with their Halloween-themed efforts, saying, "When you Trick-or-Treat for UNICEF, you get to be a hero, no matter what your costume is."

Hurricane Maria hit Puerto Rico on September 20 of this year as a Category 4 storm, after weakening slightly while passing over the island nation of Dominica at the higher strength Category 5 level, which indicates sustained winds of up to 175 mph. The storm is considered the worst natural disaster in Dominica's history, and caused widespread damage in Puerto Rico, where to this date almost 70% of the island, including hospitals and aid centers, is still without power.

Michelle Centeno, senior officer of humanitarian emergencies and executive communications for UNICEF U.S.A., said, "While conditions in Puerto Rico remain challenging, UNICEF U.S.A. is there, working to support children and families as they rebuild. The scale of need demands that we all play a role in this ongoing effort, and work closely with partners to put children first."

The Trick-or-Treat for UNICEF fundraiser began in 1950, and distributes little orange collection boxes to schools across America, Canada, Ireland, Mexico, and Hong Kong. The boxes then go to children, who carry the boxes with them as they go door-to-door on Halloween night, collecting donations of small change along with their candy. To date, the program has raised over $188 million.
